The circuit in Figure P28.75 contains two resistors, R = 2.00 kN and R2= 3.00 kN, and two capacitors, C¡ = 2.00 µF and C2 = 3.00 µF, connected to a battery with emf ɛ = 120 V. No charge is on either capacitor before switch S is closed. Determine the charges q1 and q2 on capacitors C1 and C2, respectively, after the switch is closed. (Suggestion: First reconstruct the circuit so that it becomes a simple RC circuit containing a single resistor and single capacitor in series, connected to the battery, and then deter- mine the total charge q stored in the equivalent circuit.) %3D %3D
